After discovering his Olympian roots in the 2010 movie “Percy Jackson & the Lightning Thief,” actor Logan Lerman is packing his bags once again for Camp Half-Blood and a journey into the Bermuda Triangle in pursuit of the mythical Golden Fleece in the series’ latest installment “Percy Jackson: Sea of Monsters.”

Based on the second book in the hugely popular young adult series, trouble arises in the form of Chronos, “a force so evil three of his sons — Zeus, Hades and Poseidon — destroyed him,” a trailer for the upcoming fantasy film tells us. “He’s fated to rise again to exact his vengeance on Olympus and the world.”

More than 20 million copies of Rick Riordan’s Percy Jackson books have been sold around the world and as of 2011 — which are centred around the ancient Greek gods and demi-gods co-existing with mortals in the modern world — the series had been on the “New York Times” best seller list for children’s book series for 223 weeks.

The only thing that can rescue Camp Half-Blood — an earthly sanctuary and training ground for the godlings — is the Golden Fleece, which must be fetched from the Sea of Monsters, known to humans as the Bermuda Triangle.

So Percy, with the help of Annabeth [Alexandra Daddario], Grover [Brandon T. Jackson] and Tyson [Douglas Smith], he embarks on an epic quest to retrieve the magical item.
